Analyze Media Task errors out a lot

[Liangyiu]

Describe the bug

Hey this is my first issue report on GH, so sorry if something is missing.

So I set up the full compose stack as described here.
Everything is working fine, besides some other plugins like Jellyscrub & some metadata providers not being compatible.
The thing is every time I start the Analyze Media Task, I can count on it eventually running into this error listed below.

Has anyone else encountered this before and maybe knows of a fix?

Oh and another question: Is the analysing done on the graphics card? Nvidia HW Encoding is working for streams, but during the media analysing process nothing shows up in nvidia-smi. My server has a GTX 1660 Super

Operating system

Ubuntu 22.04.3 LTS

Jellyfin installation method

Docker in privileged LXC container

Thank you for your report. I will fix the bug with the next update. Currently just chromaprint is used (audio fingerprint) so no image processing for a gpu
edit: there is a black detection, not sure if can speed that up.

My compose stack is using dotnet 7 but jellyfin stable is at dotnet 6 so you will have issues to run plugins compiled for jellyfin stable.
